Preheated coal leading-in device of coal pyrolyzing furnace

Abstract

The invention relates to a preheated coal leading-in device of a coal pyrolyzing furnace. Refractory material masonry (2) is arranged in a furnace mantle (1), blanking ports (9) are arranged on the refractory material masonry (2), the blanking ports (9) are connected with a material level control bin (10), a high material level gauge measuring hole (3), a low material level gauge measuring hole (4) and an observation hole (5) are arranged on the material level control bin (10), a raw coal gas pressure-measuring and temperature-measuring hole (6) is arranged on the furnace mantle (1), a heat insulation housing (7), a cement block (11) and a raw coal gas leading-out channel (12) are arranged below the material level control bin (10), one side of the raw coal gas leading-out channel (12) is connected with the top of a carbonization chamber (14), and the other side of the raw coal gas leading-out channel (12) is connected with a raw coal gas water-sealed valve (13). The interior is divided into two parts by the heat insulation housing filled with the heat insulation material, namely ceramic fiber, the external temperature is 600 DEG C, the internal temperature is 250 DEG C, the specific temperature required for leading preheated coal into the furnace can be met, and the preheated coal leading-in device can further save energy, improve efficiency and reduce cost.

Description

technical field [0001] The invention belongs to a coking oven, in particular to a preheating coal charging device for a coal pyrolysis furnace. Background technique [0002] At present, most of the coke ovens on the market adopt batch-type coking, that is, coal is added to the coke oven in batches, and the coal seam is set at both ends of the furnace body, and the coal is not preheated, but a separate equipment is used. Coal is dried, and the equipment scale that uses like this is big, wasted energy, and use efficiency reduces greatly. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a furnace preheating coal charging device for a coal pyrolysis furnace. It can continuously, quickly and centrally send preheated coal into the coking oven for coking. [0004] The technical solution of the present invention: a preheating coal charging device for a coal pyrolysis furnace, which includes: furnace shell 1, refractory ...
